Reznor 131458 Pilot Assembly

As a veteran tech, you know that consistent ignition is the backbone of any commercial heating system. The Reznor 131458 Pilot Assembly is a genuine OEM replacement part engineered specifically for liquid propane (LP) gas-fired units. This vertical spark pilot assembly is a critical ignition component that ensures a reliable flame to light the main burner. Designed for industrial-grade durability, it utilizes a precise spark gap to initiate the pilot, which then triggers the flame rectification sensor or thermocouple to engage the gas valve. When you are dealing with a Reznor unit heater that fails to ignite or keeps locking out on a flame sense error, swapping in the 131458 is the standard fix for restorative performance. This kit is purpose-built for LP applications and fits like a glove in compatible Reznor SCA-6 and commercial unit heaters, maintaining the high-performance standards required in professional HVACR environments. Always verify your flame probe condition when replacing this assembly.

• Genuine Reznor 131458 OEM construction ensures exact fitment and factory-grade reliability.
• Optimized for liquid propane (LP) gas systems to prevent carbon buildup and irregular flame patterns.
• Features a vertical spark pilot configuration for rapid and consistent ignition cycles.
• Durable secondary components designed to withstand high-temperature industrial combustion chambers.
• Simplified installation for contractors looking to minimize downtime during emergency service calls.

What causes a Reznor LP pilot assembly to fail?
Most failures in the field stem from carbon fouling on the electrodes, mechanical damage to the pilot tube, or a cracked ceramic insulator on the spark igniter. In high-cycle industrial environments, these components can wear down, leading to intermittent ignition or total system lockout.

Is this part compatible with natural gas heaters?
No, the 131458 is specifically calibrated for LP gas. Using this assembly in a natural gas unit could lead to improper combustion and hazardous operating conditions. Always match the orifice and assembly to your specific fuel source.

Does this kit include the flame probe?
This kit focuses on the pilot assembly and spark ignition. Depending on your specific model, such as the SCA-6, you may need to purchase the flame probe (often part number 126101) separately to ensure the control board receives a clear flame signal.
